The best types of oversized king size down alternative comforters will not only have you sleeping like royalty, but our selection down below will bring an end to your struggles of finding a king size comforter that looks great and covers your king bed while allowing for a nice overhang.

A quality comforter does not necessarily have to be expensive. Alternative down comforters can deliver a good standard of thermal features that keep you nice and cozy all year long through hot and cold seasons. And all these without you breaking your bank account for the comfort.

The features of a quality comforter are very straightforward. However, there are two things that buyers might wonder; the difference between the terms GSM and fill ounce where comforters are concerned. In fact these two can be used interchangeably as they both allude to the amount of fill used in a comforter. For instance 160 GSM means grams per square meter and 300 oz. of fill means the overall fill weight used on a comforter.

The more the fill or higher the GSM, the more the density and the more the warmth the unit is capable of.

In general, the standard size for king size comforters is around 107″ x 92″. Below we have reviewed some of the best alternative down comforters that are of high quality,  quite pocket friendly and best of all, oversized measuring at least 116″ x 98″ or more.

No more fighting for covers with your partner with the below options. Check them out!
